Centos 7 lockup
...un OpenNMS stopped working last night - no
hardware alarm lights, but keyboard/monitor/network unresponsive.
After a reboot I see a large stack of messages like this in
/var/log/messages:
----
Aug 20 14:02:34 opennms-h-03 python: SELinux is preventing
/usr/sbin/monitor-get-edid-using-vbe from mmap
_zero access on the memprotect .
***** Plugin mmap_zero (53.1 confidence) suggests *************************
If you do not think /usr/sbin/monitor-get-edid-using-vbe should need
to mmap low memory in the kernel.
Then you may be under attack by a hacker, this is a very dangerous access.

[PATCH] virtio-blk: make the queue depth configurable
Couple more bikesheddy things:
Is there ever a reason to use a non __builtin_const_p(perms)?
Maybe that should be a BUILD_BUG_ON too
BUILD_BUG_ON(!builtin_const_p_perms)
My brain of little size gets confused by the
BUILD_BUG_ON_ZERO(foo) +
vs
BUILD_BUG_ON(foo);
as it just seems like more text for the same content.
Is there any value on the "_ZERO(foo) +" I don't understand?

[RFC] Supporting ARM's SVE in LLVM
...ion) is worth highlighting because
it can simplify the vectorization of more loops.
### IRBuilder Interface:
```cpp
Value *CreatePropFF(Value* P1, Value *P2, const Twine &Name = "");
```
### Fixed-Width Behaviour:
Same as scalable.
### SelectionDAG:
See [*ISD::PROPAGATE\_FIRST\_ZERO*](#isdpropagatefirstzero).
## *shufflevector*
### Syntax:
`<result> = shufflevector <ty1> <v1>, <ty1> <v2>, <ty2> <mask>`
### Overview:
Not a new instruction but *shufflevector* is extended to accept non-constant
masks. For code that expects the origin...
